Terminal output

On starting Diablo 3 I usually see a gray fullscreen before the game loads its
ingame-login screen. But with Wine 3.12 it stops at the gray screen (which
turns black if switched to the console and back). There are a few symptoms:

- Terminating all applications in Wine does not prevent the black screen to go
away or Wine to exit.
- The winedevices.exe does not respond to a SIGTERM and needs to be terminated
with a SIGKILL.
- Wine still refuses to exit automatically even if only the wineserver64
remains.
- After terminating all processes and switching from the console to the
X-environment again the screen is still black (not sure if this is caused by
Wine or if this is a bug in the X-Server).

In the attachments is the terminal output which I had to log to disk (the game
was started via "sworddragon@ubuntu:/wine/drive_c/Program Files (x86)/Diablo
III$ setarch i386 -3 './Diablo III.exe' -launch -opengl").
